This is a few pieces of an app that needs doing, firstly a menu or activity_drawer, second is a function which will run a calculation of 4 int variables to create a total with a button which could then be connected to a MySQL database (hopefully using PHP). The final task is to fully comment everything you have done so it may be reused in other projects and zipped to us.
